error[E0658]: C-variadic functions are unstable

  = note: see issue #44930 <rust-lang/rust#44930> for more information
  = help: add `#![feature(c_variadic)]` to the crate attributes to enable

error[E0491]: in type `&'static &'a ()`, reference has a longer lifetime than the data it references

  = note: the pointer is valid for the static lifetime
note: but the referenced data is only valid for the lifetime `'a` as defined on the function body at 3:32
